never brush your teeth with an especially stiff tooth brush, is all i have to say.
we have his and hers apartments in the same house.
lol. we have a 2 family house, in which we spread thoughout and live on both floors. well, 3 floors, since i re-finished the basement.
dw takes care of the upstairs, and i, the downstairs. the birds and my man cave are in the basement.
the best part is that i have my own kitchen. we share everything in them, of course, but we have 2 or 3 of everything, so both kitchens are stocked with "our own" stuff.
My DW and I have the ultimate his & hers items. I have a "his" body, and she has a "hers" body. Though sometimes I think she believes my body is hers as well. She certainly has a host of chores for it to do.
